FLAYING IMPLEMENT Filed Oct. 28, 1958 2 Sheets-Sheet 2 All INVENTOR BY WATTORNEYS United States FLAYING IMPLEMENT Newton Halsted Williams,Newtown, Conn., assignor to Richard W. Logan, Madison, Conn.

Filed Oct. 28, 1958, Ser. No. 770,177 7 Claims. (Cl. 30--219) is exposedso that it may be used for the intended purpose. The blades are commonlyrotatable about a common pivot or axis and are of substantially the samediameter, and the frame or casing is tubular or hollow so as to receivea rotating shaft so connected to the blades as to effect theiroscillation.

' One object of my invention is to provide an apparatus of the characterdescribed which may be economically made and of relatively simpleconstruction and at the same time eflicient in operation and capable oflong use.

Still another object of the invention is to provide novel means foreffecting the oscillation of the blades from a rotating shaft. I

A still further object of the invention is to provide a connectionbetween the blades and the oscillating mechanism which may be adjustableso that different portions of the blades may be employed in use, thusrendering the tool capable of longer use without the necessity ofsharpening the teeth thereof.

Still another object of the invention is to provide a flaying implementof the character described wherein the blades will operate with aslittle friction as possible and at the same time the teeth of the bladeswill be urged into contact with eachother so as to cooperate eflicientlym use.

A still further object of the invention is to lengthen the life oftheimplement by providing teeth over the entire periphery of the bladesand connect the latter adjustably to oscillating yoke members so thatthe blades may be 'set at different positions relatively to the casingor frame and different sections of the teeth employed in use.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

on line 2-2 of aren't O i Patented Mar. 14, 1961 shaft 16 having thereona pair of oppositely disposed eccentrics 17 and 18.

The cheek member 10 is removably secured to the member 11 by means ofthe screw 20 having an enlarged head 21 at one end and the other end ofthe screw being threaded into a nut 22 secured to the cheek member 11 bythe pin 23. Aligning pins 24 (one of which is shown) are secured to thesocket 12 and may be received in openings 25 of the cheek member 10.

Secured to the cheek member 11 by the pin 23 is a hollow pivot pin 26which surrounds the screw 20 and which is provided with a flange 27. Aflange 28 is secured to the cheek member 10 by a pin 29 and betweenthese two flanges cooperating blades 30 and 31 are rotatably mountedupon the pivot member 26. These disklike blades are of circular form andare provided with peripheral teeth 33 which, as shown, extend around theentire periphery of the blades.

Between the flanges 27 and 28 and the adjacent blades are providedactuating yoke members 34 and 35 shown in Figs. 6 and 7. The member 34is adjacent the blade 30 and is provided with a flat body portion havingan opening 36 receiving the pivot member 26 so that this member isoscillatably or rotatably mounted about the pivot of the blades. Themember extends rearwardly and is bent outwardly, as shown at 37, and atits rear end provided with downwardly extending spaced arms 38 betweenwhich is snugly positioned the eccentric 18. At an intermediate portionof this member is provided a stud or pin 40 adapted to be received inone of a pair of openings 41 in the associated blade so as to connectthis actuating member nonrotatably to the blade.

The actuating member 35 is made similarly to the member 34 and isprovided with an opening 42 which receives the pivot pin 26 and is bentoutwardly, as shown at 43, and provided with spaced inwardly turned arms44 between which the eccentric 17 is snugly received. The arms 44 may bejoined by'an integrally formed bar 45 so as to strengthen theconstruction. The intermediate portion of this member also is providedwith a stud 01' pin 46 to be received in an opening 41 in the blade Asshown more particularly in Figs. 2 and 5, a circular corrugated spring47 is disposed between the flange 28 and the actuating member 34, whichspring urges the adjacent blade into contact with the cooperating bladeso that the teeth of the blades will properly cooperate. In order thatthe teeth of the blades be in contact and at the same time provide for aminimum amount of friction between the blades when the tool is in use,it will be noted from Fig. 4 of the drawing that the inner surface 48 ofeach blade is slightly dished or concave so that, while the blades willbe in contact over their peripheral portions, the intermediate portionswill be slightly out of contact and thus friction will be reduced. Eachof the blades is provided with a central opening 49 to receive the pivotmember 26.

As previously stated, the handle member 14 is hollow and within thishandle is a sleeve 56 secured to the shaft 16, which sleeve is providedwith a polygonal opening 51 to receive a similarly shaped shaft 52carried by a flexible shaft 53. The latter may be surrounded by abushing 54 having an annular channel 55 receiving a pin 56 carried byone end of a spring 57 secured in a recess 3 58 in the handle. This pinserves to detachably secure the flexible shaft to the handle of thetool.

The provision of a pair of openings 41 in each of the blades permits theblades to be turned through an angle of 180 degrees and connected to theyokes 34 and 35 so that the opposite edges thereof will be disposedoutwardly for use. Thus, when the teeth of the blades become dull whenthe blades are in one position, they may be turned through an angle of180 degrees and the teeth on the other side of the blades employed.

While I have shown and described a preferred embodiment of my invention,it will be understood that it is not to be limited to all of the detailsshown, but is capable of modification and variation within the spirit ofthe invention and within the scope of the claims.
